ApplicationsBelow are some examples of Greene Tweed’s extensive

experience of designing with plastics to optimize perfor-

mance for weight saving and corrosion resistance when

considering replacing metal components.

BearingsBearings made from Arlon® 1555, a high-performance

thermoplastic, make excellent replacements for metal

bushings in armored infantry fighting vehicles.

Seal-Connect® ConnectorsArlon® 2000 meets primary material requirements for con-

nectors due to its thermal or electrical insulation properties

and resistance to corrosive media. Seal-Connect connec-

tors withstand temperatures in excess of 480°F (250°C)

steam and high-pressure oil/sea water environments

without any significant degradation in properties.

Valve Plates—Plates/Seats/BodiesPEEK valve plates have excellent stress resistance, durabil-

ity and fatigue endurance while providing a long life span.

PEEK is an effective metal replacement in extremely harsh

environments due to its superior chemical resistance.

SealsGreene Tweed uses a variety of engineered plastics in its

custom-designed seals. Exact combinations of material and

configuration vary based on the sealing conditions faced,

and are selected on a case-by-case basis in order

to ensure optimum performance.

Piston ComponentsGreene Tweed has redesigned pistons to incorporate the

piston and sealing element in one piece, thus achieving sig-

nificant weight savings. Piston rings which utilize Arlon® 1260

feature excellent high-temperature and tribological properties.

Arlon® to Rubber BondingGreene Tweed has the capability to bond elastomers to

plastic components. Arlon® has been bonded to elastomers

such as FVMQ, HNBR and NBR.

Pump ComponentsPEEK is an ideal stainless steel substitute in impeller wheels,

resulting in significant wear and noise reduction. Stainless

steel requires multiple machine parts whereas only one

molded part is required for PEEK.

WR®525 is a thermoplastic composite consisting of carbon fiber in a PEEK matrix. WR works well in bushing and case wear ring applications. WR offers the following characteristics metallic wear products do not:

• High strength to weight ratio• Low coefficient of thermal expansion• Excellent chemical resistance• Nongalling/nonseizing properties• Low coefficient of friction

• Impact and thermal shock resistance

These benefits enable the pump user to increase pump efficiency by running tighter wear ring clearances and, at the same time, decrease potential pump damage during

cavitation or with in-line bearing failures.

Threaded FastenersPEEK is ideal for threaded fasteners due to its resistance to a wide range of inorganic and organic materials. Fasteners are extremely tough with excellent impact resistance and fatigue strength over a wide range of temperatures. The benefits of using these materials include chemical/corrosion resistance,toughness, impact resistance and fatigue strength.

Sensor HousingPEEK adds an excellent balance of chemical,mechanical and thermal properties to sensor housing. The properties afford-ed by PEEK helped bring a new measuring system into full compliance with rigid hygienic requirements for the treatment and handling of biologically sensitive media. PEEK is well suited in this application because it provides weight savings and corrosion resistance.
